When Li Xu woke up, he was still there, but his home was gone. Looking at the gorgeous but unfamiliar ceiling, he couldn't even turn over. Li Xu felt that he was still there, but in fact the figure seemed to have been gone for a while.

Li Xu, who had been a cub for a week, got some information. Good news: His brother is Li Chengqian Bad news: His brother is Li Chengqian! ! !
